We discuss the problem of meteor plasma formation and
consequently of radio-wave scattering from an ionized meteor trails
produced by rotating meteoroids. The problem is solved under the following
approximations: the meteoroid is represented by a cube, its rotation axis
is perpendicular to the velocity vector, meteoroid deceleration can be
neglected, the only acting ablation mechanism is the evaporation, the
deionization effects are negligibly small. In this case the ambipolar
diffusion approximation applies, and, supposing that the source of free
electrons is known, the distribution of free electrons inside a trail,
, considered as a function of position and time, can be
computed. It is shown that the electron distribution along a trail axis
oscillates, which is not the case with respect to the radial distribution.
The function found is then used for the solution of the
problem of the scattering of radio-waves on the underdense-type
trails produced by rotating particles. The values for amplitude-time as
well as phase-time characteristics computed under the above assumptions
differ only very slightly from those computed when meteoroid rotation is
not taken into consideration.
